Optimization of layer structure of sintering mixture composition in order to stabilize the thermal conditions during sintering
Journal Title: Metallurgical and Mining Industry - Year 2017, Vol 9, Issue 2
Abstract
It was found that the thermal conditions of agglomerate sintering and the gas permeability of the charge layer depend on the segregation processes occurring in the layer of the feed material, which is due to the type of used charging device. The authors solved the optimization problem to determine the control actions on the composite chute providing the formation of the charge layer with the desired properties. A control algorithm of sintering machine charging device was proposed in order to form an optimal structure of the charge layer prepared for sintering, which in complex takes into account the impact of segregation of pellets and gas dynamics of formed layer when loading material to pellet cars. The results of the active experiment with the sintering of agglomerate are given and the influence of the conditions of the charge layer formation on the thermal conditions and the productivity of the process is analyzed. The results of calculations allowed us to establish the optimal values of the sections inclination angles of composite feed chute providing the best fit to the optimal distribution of solid fuel and a reduction on height of pressure losses of the sintering mixture layer
